Hi Everyone,
What's a good price for 12 gram CO2 cartridges? I just got my first paintball pistol and wanted to figure out where to get decently priced CO2 for my prized new pistol.

Is $0.50 a cartridge a decent value or is that average/fair in terms of market prices? I found something on Amazon for $19.95 per 40. (http://www.amazon.co..._pr_product_top) Is this worth the money to purchase?
